Recommended: The Efficient Market Hypothesis and Its Forms: Theoretical Aspects and Empirical Studies

The concept of Efficient Market Hypothesis has weak bases. The efficacy of these assumption depends upon strength of one of the three situations. Coherent investment decisions, liberated irrational investment decisions, and arbitrage. In practice, none of these three conditions are valid. An alternate method, to explain capital market performance, based on psychology is gaining significance in the field of finance. The concept of 'efficient market hypothesis' was introduced by Eugene Fama in mid-1960s. According to this concept, the powerful struggle in the capital market leads to reasonable valuing of debt and equity securities. The perception is based on the replication of related evidence in market prices of the securities. If only past information is reflected in 'weak-from efficient markets; past as well as present information is reflected in 'semi-strong form efficient markets'; past, present, and future information is reflected in 'strong-form efficient markets'. Efficient market hypothesis has reflective effects for corporate finance and investment management. Implications for corporate finance 1. Managers cannot dupe the market through imaginative accounting. 2. Companies cannot effectively stretch matters of debt and equity. 3. Managers cannot successfully venture in securities market. 4. Managers can gain paybacks by giving responsiveness to market prices. Implications for investment management 1. If the market is efficient in weak-form, investors cannot obtain unusual returns by evaluating related past information about the securities. However, it is possible to obtain unusual returns by examining existing information and upcoming information. Thus, investment tools like strainer plan, technical analysis will not be ac... ... middle of paper ... ...the motivation to trade, and tiny inefficiencies might not be priced away. Limitations to Arbitrage Ideally, if two securities are mispriced relative to their risk one is sold-out short and also the different purchased. The sale of one and get of the other can drive each toward their economical worth. In follow, there are four issues related to this. It is unsure once, if ever, costs can come back to equilibrium. The mispricing may become even a lot of pronounced within the meanwhile, doubtless forcing the businessman to shut the position. Two assets seldom have identical risks. If there are not any shut substitutes for a given security, no arbitrage could also be potential. Arbitrageurs have restricted access to capital. Solely the foremost obvious mispricing is exploited. Arbitrageurs might face restrictions on mercantilism by the owners of the capital they use.

    Fama propounded EMH, in 1965, stating that provided all available information is used, market prices will reflect reasonably accurate approximations of the inherent present value of securities; the employment of this information would render agents’ actions rational. Ball expands on this by suggesting that competitive markets lead to costs falling in line with the employment of information.

  • Stock Markets: The Castle in the Air vs The Firm Foundation Theory

    1430 Words  | 3 Pages

    The Castle in the Air theory was introduced by John Maynard Keynes, an well known economist and successful investor of the 1930s. It was Keynes’ theory that the keys to investing came from supernatural or psychic means. He applied psychological rather than financial principles to the study of the stock market. He believed that it was not only too difficult but also quite time consuming to determine the intrinsic value that would yield a promising return on investments. He thought that it should not take all of that. He proposed that the best way to do so was estimating which investment situations that the public would focus on and then buying “before the crowd.” In other words, instead of picking out six out of a hundred stock based on how attractive they may have looked on the outside, it was better to select those stocks that the public were more likely to like the best. Or more so to predict what an average opinion of the best stocks are likely to be.

  • The Efficient Market Hypothesis

    774 Words  | 2 Pages

    The efficient market hypothesis has been one of the main topics of academic finance research. The efficient market hypotheses also know as the joint hypothesis problem, asserts that financial markets lack solid hard information in making decisions. Efficient market hypothesis claims it is impossible to beat the market because stock market efficiency causes existing share prices to always incorporate and reflect all relevant information . According to efficient market hypothesis stocks always trade at their fair value on stock exchanges, making it impossible for investors to either purchase undervalued stocks or sell stocks for inflated prices. As such, it should be impossible to outperform the overall market through expert stock selection or market timing, and that the only way an investor can possibly obtain higher returns is by purchasing riskier investments . In reality once cannot always achieve returns in excess of average market return on a risk-adjusted basis. They have been numerous arguments against the efficient market hypothesis. Some researches point out the fact financial theories are subjective, in other words they are ideas that try to explain how markets work and behave.

  • Essay On Market Manipulation

    828 Words  | 2 Pages

    The most frequently discussed among the market manipulation is “long” market power manipulation also known as a “corner” or a “squeeze” (Pirrong, 2010). These occurs when a trader buy a vast number of future contracts. The trader, therefore, is able to influence the price artificially through controlling supply of the commodity of the future contract. This could affect to short sellers. In the futures market, the shorts sell more contracts than quantity available that actually can be delivered at maturity. It is because the contracts are used as hedgers and speculators to transfer risks. These contracts can be offset between the shorts and longs. The short have to either provide the commodity or pay differences between spot price and futures price at maturity unless the contracts are offset between the long and the short. However, if the large long acts like a monopolist through controlling over the supply, the shorts would be cornered and pay distorted amount to the monopolist, meaning that artificial price w...

  • Market Efficiency

    Stock market prediction is the method of predicting the price of a company’s stock. It is believed that stock price is lead by random walk hypothesis. Random walk hypothesis states that stock market price matures randomly and hence can’t be predicted. Pesaran (2003) states that it is often argued that if stock markets are efficient then it should not be possible to predict stock returns. In fact, it is easily seen that stock market returns will be non-predictable only if market efficiency is combined with risk neutrality. On the other hand it is also been concluded that using variance ratio tests long horizon stock market returns can be predicted....

  • Essay On Capital Asset Pricing Model

    1344 Words  | 3 Pages

    Capital Asset Pricing Model (CAPM) is an ex ante concept, which is built on the portfolio theory established by Markowitz (Bhatnagar and Ramlogan 2012). It enhances the understanding of elements of asset prices, specifically the linear relationship between risk and expected return (Perold 2004). The direct correlation between risk and return is well defined by the security market line (SML), where market risk of an asset is associated with the return and risk of the market along with the risk free rate to estimate expected return on an asset (Watson and Head 1998 cited in Laubscher 2002).

  • A Random Walk Down Wall Street

    3851 Words  | 8 Pages

    Chapter 11 closes our discussion with several insights into the efficient market theory. There have been many attempts to discredit the random walk theory, but none of the theories hold against empirical evidence. Any pattern that is noticed by investors will disappear as investors try to exploit it and the valuation methods of growth rate are far too difficult to predict. As we said before the random walk concludes that no patterns exist in the market, pricing is accurate and all information available is already incorporated into the stock price. Therefore the market is efficient. Even if errors do occur in short-run pricing, they will correct themselves in the long run. The random walk suggest that short-term prices cannot be predicted and to buy stocks for the long run. Malkiel concludes the best way to consistently be profitable is to buy and hold a broad based market index fund. As the market rises so will the investors returns since historically the market continues to rise as a whole.
